This
is the first of two articles addressing the role that low-molecular-weight
polyolefins and wax additives have in the formulation and performance of
hot-melt adhesives. This part examines wax additives available to the
formulator; their composition, characteristics, and manufacture; and general
information about their use. Part two will address specific characteristics of
various types of polyolefins and their role in hot-melt adhesives, including
